Answer:
Mark is 9 and his brother is 14.
The expression for Mark: 23 - 9 = 14
The expression for his brother: 23 - 14 = 9
Step-by-step explanation:
We know that 14 is 5 more than 9, and Mark is the younger one so he would be 9 and his brother 14. 9 + 14 also equals 23, so thats how you know you have the right answers.
5(x + 3) + 9 = 3 (x - 2) + 6
5x + 15 + 9 = 3x - 6 + 6
5x + 24 = 3x
5x - 3x = -24
2x = -24
x = -24/2
x = - 12

Answer:
measure of major arc BEA = 224.4° Option D
Step-by-step explanation:
Given that, measure of inscribed angle ∠BEA = 67.8°
Firstly we will find the central angle.
Suppose O is the center of given circle
So, ∠AOB = 2∠AEB
∠AOB = 135.6°
The measure of arc AB is same as the measure of its central angle.
So, measure of AB arc = 135.6°
Now complete circle measure = 360
Measure of major arc AEB = 360° - measure of arc AB
= 360° -135.6°
= 224.4°
That's the final answer.
